Receiving a Shipment of Bands

The bander should immediately check the numbers on the bands (not those on
the envelopes or boxes) and verify the accuracy of each shipment of bands. The
appropriate Bird Banding Office should be notified immediately if there is a
discrepancy between the band numbers on the Acknowledgement Letter (U.S.) or
Issue Slip (CWS) and the band numbers on the bands. The bands in that series
should not be used until the discrepancy is cleared up.

The Acknowledgement Letter should be signed and returned to the BBL. In
Canada, the Issue Slip should be returned to the CWS office only if there is a
discrepancy.
